WILLIAM M. TODD, OF LAFAYETTE, INDIANA, ASSIGNOR OF ONE-HALF TO ISAAC H.CANNON, OF SAMEPLACE.

STUMP-PULLER.

SPECIFICATION forming part of Letters Patent No. 548,278, dated October22, 1895.

Application and July 2,1395. serai No. 554,698. (No model.)

To all whom it may concern:

Be it known'that I, WILLIAM M. TODD, a citizen ot' the United States,residing at Lafayette, in the county of Tippecanoe and State of Indiana,have invented certain new and useful Improvements in Stump-Fullers, ofwhich the following is a specication.

My said invention relates to that class of stump-pullers having verticalwinding-drums and generally operated by horsepower; and it consists incertain improvements in details of construction and arrangements-ofparts of such machines, as will be hereinafter more particularlydescribed and claimed.

Referring to the accompanying drawings,l which are made a part hereof,and on which similar letters and numerals of reference indi# catesimilar parts, Figure l is a perspective view illustrating myimprovedstump-puller as it appears in use; Fig. 2, a vertical sectional view,with the winding-drum in elevation, as seen when looking in thedirection indicated by the arrows from the dotted line 2 2 in Fig. 3Fig. 3, a horizontal sectional view on the dotted line 3 3 in Fig. 2Fig. 4.-, a side elevation with the winding-head at right angles withthe position shown in the other yfigures and unshipped or raised out ofengagement with the winding-drum; and Fig. 5 a detail View of the lowerend of the unshipping-lever.

In said drawings the portions marked A represent the base of theframework of my improved stump-puller; B, the upper portion of saidframework; C, the winding-drum; D, the winding-head; E, the operatinglever "or sweep; F, the operating rope'or chain; G, the stay rope orchain; H, the pawl or detent; I,

a lever for operating said pawl or detent, andv J the unshipping deviceor lever.

The frame, composed of the membersA and B, is preferably so formed thatsaid members come together at one end, where they are directly united bythe bolt 1, and at the.k other end they are connected by the standards2. Upon the upper side of the frame part Bis a circular track b, uponwhich the windinghead D rests and revolves when the machine is inoperation. Bearings are formed in these parts A and B to receive theends or gudgeons of the winding-drum C. The structure as a whole ispreferably mounted on timbers or runners B, upon which it may beconveniently transported from place to place.

The winding-drum C is mounted vertically in bearings in the frame A Band has the operating-rope F attached thereto, which rope is woundthereon in the operation of the machine. At its lower end just above thebearing or gudgeon it is provided with ratchetteeth, as shown mostplainly in Fig. 3, with which the pawl or detent H is adapted to engage,said ratchet-teeth being formed with their faces in line with the axisof said winding-drum. At the upper end larger and differentratchet-teeth c are formed, and with these corresponding ratchet-teethon the lower side of the Winding-head Dwill normally engage. ing sternc', extending into a perforation in the winding-head, as shown mostplainly in Fig. 2, which stern serves as an axle around which saidwinding-head will revolve.

The winding-head D is loosely mounted on the track b on the frame and isadapted to revolve thereon. Its lower surface has large ratchet-teeth d,adapted, when said head is in its normalposition, to engage with thecorresponding large ratchet-teeth on the winding-drum C, but which arealso adapted (upon occasion) to be lifted out of engagement with saidwinding-drum, as shown in Fig. 4.

The lever or sweep E is attached to the wind- It has also a centralupwardly-project-l ing-head D and is the means by which power is appliedto said winding-head, as is usual,` from the horses or other means forapplying force.

The rope F is attached at one end to the winding-drum C and at the otherend to the stump which is to be displaced. The operation ofthe machinein the winding of the drum winds up this rope and pulls the stump, asisillustrated and will be readily understood.. l

The rope G is a stay-rope (or chain) acting oppositely to the pull ofthe machine and is connected at one end to a point at or near the lowerside of the machine and at the other end by means of a clevis G to apoint at'or near the upper side of the machine. The means of connectingsaid clevis to the proper point on the machine is usually the cross pinor bolt g, which tits in a suitable notch or de- IOC) pression in theadjacent face of the frame part B, as shown :most plainlyin Fig. 2. Thisrope being connected at both the upper and lower portions of the machineholds it steadily and Without tipping, no matter how far up the rope Fmay be wound on the drum C.

The pawl or detent H is mounted -in a horizontal bearing in the lowerframe part A and is provided with a preferably square end which projectsinto the path of the ratchet formed on the lower end of the windingdrumC and is adapted to engage with theteeth of said ratchet. A spring hnormally holds this pawl or detent forward into suchen gagement.

A lever I, suitably pivoted, is connected to the rear end of the pawl ordetent II and is adapted to force the same back out of engagement whendesired. Theweight of ,this lever and the strength of this spring -h areso proportioned relatively to each other `that when the lever `is thrownin one directionras shown bythe dotted lines in Fig. 2, the spring beingfree to operate is suiicient to hold said pawl or detent into engagement`with the,

ratchet; but when said leveris thrownlin the other direction, as showninFig. 4, its weight is suflcient to compress the spring and `hold thepawl or detent outot engagement with the ratchet. Thus, when itisdesired to unwind the rope, all that is necessary is to `throw thislever I into that position where its weight will operate to compress thespring, when the winding-drum will be relieved and held -relieved fromthe operation of the detent.

The unshipping-lever J `is adapted `to rest over the track b, and its`engaging end is forked to pass astride the central and downwardly-projectin g portion of the winding-head D, as shown most plainly in Fig.lLandis thus suited to the work of raisin g-the winding-head out ofengagement with the drum. When the pawl or detent -I-I and winding-headD are both thrown outof engagement with the windingdrum, obviously saidwinding-drum is entirely free to be run back, as desired. While thisunshipping-lever may be made all in one piece, if desired, I prefer tohave its handle J in a separate piece, and the head J being of iron,with a suitable socket for lsaid handle, said handle may thus be acommon wooden handspike, adapted to be inserted or removed at pleasure,while the head .I will commonly remain in place, ready to be used uponany occasion, as desired.

Having thus fully described my said invention, what I claim as new, anddesire to secure by Letters Patent, is-

1. The combination, ina stump puller, of the frame-work, a winding drumvertically mounted in bearings in said frame-work and provided witha'ratchet at the lower end, a pawl or detent II mounted in horizontalbearings in said frame-work and adapted to engage with said ratchet, aspringlh adapted to hold said pawl or detent normally into saidengagement, and a lever I by which said pawl or detent may be thrown outof engagement, saidlever'beingpivoted as described, and havingthatproportion'of weight that will enable it to overcome the spring and holdsaid detent out of engagement when desired, substantially as shown anddescribed.

2. The combination, in a stump puller, of the frame-work constructed asdescribed, a vertical winding-drum mounted in bearings in saidframe-work and provided with a retaining ratchet at the lower end andlarge vertically faced ratchet teeth at the upper end with a centralAspindle extending -up inside of and to a point considerably above saidratchet teeth, a pawl I-I,fa `spring h adapted to `automatically forcesaid pawl into engagement with the retaining ratchet at the lower end, alever Iadapted to shift and hold said ratchet outof engagement, aw-inding head at theupper end having a central socket adapted to titoverthe spindle of the winding drum and `provided with largevertically-faced ratchet teethadapted to engage with the correspondingratchet teeth at the upper endof said winding drum and alsofitted to`receive the operating lever yorsweep, a circular track on the uppersurfaceof the frame-work, and corresponding track portions -on the underside of the winding head,said several parts being constructed, arrangedand operating substantially as shown and described.

3. The combination, ina stump puller, ot the frame-work composed `of thebase A and the upper portion B connected by the bolts and standards land 2 and mounted on the 4runners R, the vertical winding drum C havon astem extending up from the winding drum and engaging with the drivingratchet thereof,thefdriving lever or sweep E, the operating rope orchain F, thestay rope or chain G connected to a stay post or stump at acentral point and to theframe part A at one end and to a clevis Gattached to the frame part B `at the `other end, the automaticallyoperating pawl H, the lever I for operating said pawl, and thebifurcated lever J `for unshipping or disconnecting the driving headfrom the winding block, all substantially as set forth.

In witness whereof I have hereunto set my hand and seal, at Lafayette,Indiana, this 26th day of llune, A. D. 1895.
